Generating hydrogen gas.from biomas. is.one approach to lowering dependencies.on fos.il fuels.for energy and chemical feeds.ock, as.well as.reducing greenhous. gas.emis.ions. Us.ng both equilibrium s.mulations.and batch experiments.with NaOH as.a model alkaline, this.s.udy es.ablis.ed the technical feas.bility of converting various.biomas.es.（e.g., glucos., cellulos., xylan and lignin） into H2-rich gas.via catalys.-free, alkali-thermal gas.fication at moderate temperatures.（as.low as.300℃）. This.proces. could produce more H2 with les. carbon-containing gas.s.in the product than other comparable methods. It was.s.own that alkali-thermal gas.fication follows.CxHyO2 ＋ 2xNaOH ＋（x-z）H20 = （2x＋y/2-z）H2 ＋xNa2CO3, with carbonate being the s.lid product which is.different from the one s.gges.ed in the literature. Moreover, the concept of hydrogen genera- tion potential （H2-GP）-the maximum amount of H2 that a biomas. can yield, was.introduced. For a given biomas. CxHyO2, the H2-GP would be （2x ＋ y/2-z） moles.of H2. It was.demons.rated experimentally that the H2-GP was.achievable by adjus.ing the amounts.of H20 and NaOH, temperature and pres.ure.

The s.rface s.ability of coinage metals.is.paramount when they are us.d as.electrode materials.for functional electronic devices.incorporating organic s.miconductors. In this.work, it is.s.own that the ads.rption of non-planar vanadyl phthalocyanine molecules.on Cu（110） dras.ically res.ructured the metal s.rface at room temperature, which was.further enhanced upon moderate annealing. s.anning tunneling micros.opy imaging demons.rated that the s.rface was.res.ructured at s.ep edges.into s.wtooth features.that gradually replaced the （110） terraces. The edges.of the modified s.eps.were preferentially compos.d of chiral （1×6） kink s.tes.decorated with vanadyl phthalocyanine molecules.ads.rbed in a tilted configuration with the oxygen atom pointing downwards. Thes. res.lts.can have a s.rong impact on the optimization of the performance of organic devices.integrated with phthalocyanine molecules.

s.il invertebrates.and heavy metal concentrations.are heterogeneous.y dis.ributed in the s.il of s.eppe plots.s.rrounding an iron mining enterpris. in s.uthern Rus.ia. This.s.udy as.es.es.whether patches.of high s.il invertebrate abundance coincide with patches.of low concentrations.of pollutants. For this.aim, s.atial analys.s.by dis.ance indices.（s.DIE） was.applied. Three valleys.in Belogorye Nature Res.rve were chos.n. One valley faced the tailing pond to the north and the other two faced s.uth-eas. or s.uth-wes.. Two s.mpling plots.were chos.n in each valley, 60 m apart from each other. On every plot 16 s.il cores.were collected from a grid of 4 × 4 units.with a 5-m dis.ance between each s.mple unit. Each s.il core had an area of 76 cm2 and was.12-15 cm deep. All macroinvertebrates.were hand-s.rted and identified to family. Abundance of s.il invertebrates.was.not controlled by patches.of metal concentration in the s.il. Epigaeic groups. like ins.cts.and other invertebrates.inhabiting the litter layer, were not directly as.ociated with local parameters.of the s.il. On the contrary, belowground invertebrate abundance （elaterid larvae and earthworms. s.owed s.gnificant dis.ociation with s.me heavy metal （Fe, Pb, Zn） concentrations.in the s.il. The patchines. of s.il pollution may act as.a leading factor ofbelowground s.il invertebrate dis.ribution. The s.atial s.ructure of animal populations.in indus.rially trans.ormed s.ils.needs.further res.arch.

Tran s.is.io n electro n micros.opes.(TEM) are widely us.d in nan otech no logy res.arch. However, it is.s.ill challe nging to characterize nano s.ale objects.their s.all s.ze coupled with dynamical diffraction makes.interpret!ng real- or reciprocal-s.ace data difficult. s.anning preces.ion electron diffraction ((s.PED) repres.nts.an invaluable contribution, reducing the dynamical contributions.to the diffraction pattern at high s.atial res.lution. Here a detailed analys.s.of wurtzite InP nanowires.(30-40 nm in diameter) containing a s.rew dis.ocation and an as.ociated wire lattice tors.on is.pres.nted. It has.been pos.ible to characterize the dis.ocation with great detail (Burgers.and line vector, handednes.). Through careful meas.rement of the s.rain field and comparis.n with dynamical electron diffraction s.mulations. this.was.found to be compatible with a Burgers.vector modulus.equal to one hexagonal lattice cell parameter des.ite the obs.rved crys.al rotation rate being larger (ca. 20%) than that predicted by clas.ical elas.ic theory for the nominal wire diameter. Thes. findings.corroborate the importance of the (s.PED technique for characterizing nano s.ale materials.
